Twitter, Reddit, HN don't always have the consistency of conversation that two people talking do.

Even here, I'm responding to you on a thread that I haven't been in on previously.

There's also a lot more material out there in the format of Stack Exchange questions and answers, Quora posts, blog posts and such than there is for consistent back and forth interplay between two people.

IRC chat logs might have been better...ish.

The cadence for discussion is unique to the medium in which the discussion happens. What's more, the prompt may require further investigation and elaboration prior to a more complete response, while other times it may be something that requires story telling and making it up as it goes.
